A transcript of the joint conference call is attached hereto as Exhibit 99.1 and a link to the recording of the call is available on Odyssey’s website at https://ir.odysseymarine.com. The transcript of the joint conference call and the information set forth therein shall not be deemed to be filed for purposes of Section 18 of the Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise be subject to the liabilities of that section, nor shall it be deemed to be incorporated by reference in any filing under the Securities Act of 1933, as amended (the “Securities Act”) or the Exchange Act.

Forward-Looking Statements

This Current Report on Form 8-K and the transcript of the joint conference call attached hereto as Exhibit 99.1 contain forward-looking statements based upon Odyssey’s and AOM’s current expectations. This communication contains “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements are identified by terminology such as “believe,” “may,” “will,” “estimate,” “continue,” “anticipate,” “intend,” “could,” “should,” “would,” “project,” “plan,” “expect,” “goal,” “seek,” “future,” “likely,” or the negative or plural of these words or similar expressions. These statements are only predictions. Odyssey and AOM have based these forward-looking statements largely on their then-current expectations and projections about future events, as well as the beliefs and assumptions of management. Forward-looking statements are subject to a number of risks and uncertainties, many of which involve factors or circumstances that are beyond each of Odyssey’s and AOM’s control, and actual results could differ materially from those stated or implied in forward-looking statements due to a number of factors, including but not limited to: (i) the risk that the conditions to the closing or consummation of the proposed Merger are not satisfied, including the failure to obtain stockholder approval for the proposed Merger; (ii) uncertainties as to the timing of the consummation of the proposed Merger and the ability of each of Odyssey and AOM to consummate the transactions contemplated by the proposed Merger; (iii) risks related to Odyssey’s and AOM’s ability to correctly estimate their respective operating expenses and expenses associated with the proposed Merger, as applicable, as well as uncertainties regarding the impact any delay in the closing would have on the anticipated cash resources of the resulting combined company upon closing and other events and unanticipated spending and costs that could reduce the combined company’s cash resources; (iv) the occurrence of any event, change or other circumstance or condition that could give rise to the termination of the proposed Merger by either Odyssey or AOM; (v) the effect of the announcement or pendency of the proposed Merger on Odyssey’s or AOM’s business relationships, operating results, and business generally; (vi) costs related to the proposed Merger; (vii) the outcome of any legal proceedings that may be instituted against Odyssey, AOM, or any of their respective directors or officers related to the Merger

Agreement or the transactions contemplated thereby; (vii) the ability of Odyssey or AOM to protect their respective intellectual property rights; (viii) competitive responses to the proposed Merger; (ix) unexpected costs, charges or expenses resulting from the proposed Merger; (x) whether the combined business of AOM and Odyssey will be successful; (xi) legislative, regulatory, political and economic developments; and (xii) additional risks described in the “Risk Factors” section of Odyssey’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025, filed with the SEC on March 31, 2026. Additional assumptions, risks and uncertainties are described in detail in Odyssey’s registration statements, reports and other filings with the SEC, which are available on Odyssey’s website, and at www.sec.gov. Accordingly, you should not rely upon forward-looking statements as predictions of future events. Neither Odyssey nor AOM can assure you that the events and circumstances reflected in the forward-looking statements will be achieved or occur, and actual results could differ materially from those projected in the forward-looking statements. The forward-looking statements made in this communication relate only to events as of the date on which the statements are made. Except as required by applicable law or regulation, Odyssey and AOM undertake no obligation to update any forward-looking statement to reflect events or circumstances after the date on which the statement is made or to reflect the occurrence of unanticipated events. Investors should not assume that any lack of update to a previously issued “forward-looking statement” constitutes a reaffirmation of that statement.
